Sorry to start a conversation that has been so much talked about already. But my intake is awesome. I went to Injen the other day to make sure that the intake fits properly onto our cars. The guy at injen did the install in about 45 mins or so. It seemed really simple to do. Anyways. He told me a lot of cool info, like the disconecting the battery is a myth, and the idling for 20 is as well. At first, I was like what???? But he was right. I just started the car and drove off. All I can say about the performance is wow!!! The power it gives and the sound is just Oh so Cool. In all, I would highly recomend this to all people to buy..
